What are the potential issues with using fsockopen() in PHP to send UDP packets for Wake-on-LAN functionality?

One potential issue with using fsockopen() in PHP to send UDP packets for Wake-on-LAN functionality is that it may not work correctly due to the unreliable nature of UDP. To solve this issue, you can use socket functions like socket_create(), socket_sendto(), and socket_close() to send the UDP packets instead. 

<?php
$mac_address = '00:11:22:33:44:55';
$broadcast_ip = '255.255.255.255';
$port = 9;

$socket = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP);
socket_set_option($socket, SOL_SOCKET, SO_BROADCAST, 1);
socket_sendto($socket, 'magic_packet_data', strlen('magic_packet_data'), 0, $broadcast_ip, $port);
socket_close($socket);
?>
